  • Patent number: 9346421
    Abstract: A vehicle includes a battery supported by an elastic member. The vehicle is provided with a connector that is electrically connected to a connector on the battery. The connector on the vehicle is switched between an unlock state in which the movement of the connector on the vehicle is allowed to follow the oscillation of the battery, and a lock state in which the movement of the connector on the vehicle is restricted. Accordingly, it is possible to prevent a stress from being applied to the connector on the battery and the connector on the vehicle when a vehicle is travelling, and it is possible to smoothly connect the connector on the battery and the connector on the vehicle when a user mounts the battery on the vehicle.
